Examine substrates, areas, and conditions where installation of resilient products will occur, with Installer present, for compliance with manufacturer's requirements. Verify that substrates and conditions are free of defects and fully comply with manufacturer's specified requirements for resilient product installation. Determine adhesion and dryness by performing flooring manufacturers recommended bond test and ASTM Standard F2170 test method using in Situ Probes to test for relative humidity. Concrete slabs moisture levels cannot exceed manufacturer s recommendations for moisture. Provide University's Representative with test results prior to installation for all concrete slabs

4 B. Concrete Subfloors: Verify that concrete slabs comply with ASTM F 710 and the following: 1. Slab substrates are dry and free of curing compounds, sealers, hardeners, and other materials that may interfere with adhesive bond.
